Depending on the context of the game... you will get the volume to justify the limp to flop a set, occasionally. However, personally I wouldn't limp unless I have 2 limpers in front of me.

However, overlimping will sometimes encourage the right type of player behind you to overlimp as well. Thus creating the volume you are looking for. It is a hard situation to explicitly describe, but you know it when you see it.
